BIGIPINETPORTEXHAUSTION BIGIPNOTIFYOBJMSG = INET PORT EXHAUSTION

I've got a VIP with a SNAT pool with 3 addresses (10.100.82.174, 10.100.82.230 and 10.100.82.231). From time to time I get a port exhaustion message for one of the addresses of the pool (and not at peak traffic moments? And never at the same server).

Is this a problem or just an informational message? If one SNAT address is "full" it should use the other SNAT addresses, right?
